BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum X morifolium andhereinafter referred to by the name ‘Aduro Bronze’.

The new Chrysanthemum plant is a product of a planned breeding programconducted by the Inventor in Oostnieuwkerke, Belgium. The objective ofthe breeding program is to create new uniformly mounding and freelyflowering Chrysanthemum plants with unique and attractive ray floretcoloration.

The new Chrysanthemum plant is a naturally-occurring whole plantmutation of Chrysanthemum X morifolium ‘Aduro Violet’, not patented. Thenew Chrysanthemum plant was discovered and selected by the Inventor as asingle plant from within a population of plants of ‘Aduro Violet’ in acontrolled greenhouse environment in Oostnieuwkerke, Belgium in October,2015.

Asexual reproduction of the new Chrysanthemum plant by vegetativeterminal cuttings was first conducted in a controlled greenhouseenvironment in Oostnieuwkerke, Belgium in January, 2016. Asexualreproduction by vegetative terminal cuttings has shown that the uniquefeatures of this new Chrysanthemum plant are stable and reproduced trueto type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Aduro Bronze’. These characteristicsin combination distinguish ‘Aduro Bronze’ as a new and distinctChrysanthemum plant:

-   -   1. Upright, outwardly spreading and uniformly rounded plant        habit; moderately vigorous growth habit.    -   2. Freely branching habit; dense and full plant habit.    -   3. Dark green-colored leaves.    -   4. Uniform and freely flowering habit.    -   5. Long flowering period.    -   6. Decorative-type inflorescences with ray florets that are        initially red purple in color becoming greyed orange in color        with subsequent development giving the inflorescences a        bi-colored appearance.

Plants of the new Chrysanthemum can be compared to plants of themutation parent, ‘Aduro Violet’. Plants of the new Chrysanthemum differprimarily from plants of ‘Aduro Violet’ in the followingcharacteristics:

-   -   1. Plants of the new Chrysanthemum are more uniform than plants        of ‘Aduro Violet’.    -   2. Ray florets of plants of the new Chrysanthemum are initially        red purple in color becoming greyed orange in color with        subsequent development giving the inflorescences a bi-colored        appearance whereas ray florets of plants of ‘Aduro Violet’ are        pink and violet in color.

Plants of the new Chrysanthemum can be compared to plants of theChrysanthemum X morifolium ‘G19ADU09MA’, disclosed in U.S. Plant patentapplication Ser. No. 15/732,899. In side-by-side comparisons, plants ofthe new Chrysanthemum differ primarily from plants of ‘G19ADU09MA’ inray floret color as ray florets of plants of the new Chrysanthemum areinitially red purple in color becoming greyed orange in color withsubsequent development giving the inflorescences a bi-colored appearancewhereas ray florets of plants of ‘G19ADU09MA’ are dark red purple incolor.

Plants of the new Chrysanthemum can be compared to plants of theChrysanthemum X morifolium ‘GED18ADU7P’, disclosed in U.S. Plant patentapplication Ser. No. 15/732,905. In side-by-side comparisons, plants ofthe new Chrysanthemum differ primarily from plants of ‘GED18ADU7P’ inray floret color as ray florets of plants of the new Chrysanthemum areinitially red purple in color becoming greyed orange in color withsubsequent development giving the inflorescences a bi-colored appearancewhereas ray florets of plants of ‘GED18ADU7P’ are initially red purplein color becoming light purple and lighter red in color with subsequentdevelopment giving the inflorescences a bi-colored appearance.

Plants of the new Chrysanthemum can also be compared to plants of theChrysanthemum X morifolium ‘Vigorelli Dark Orange’, disclosed in U.S.Plant Pat. No. 28,180. In side-by-side comparisons, plants of the newChrysanthemum differ primarily from plants of ‘Vigorelli Dark Orange’ inthe following characteristics:

-   -   1. Plants of the new Chrysanthemum are not as vigorous as plants        of ‘Vigorelli Dark Orange’.    -   2. Plants of the new Chrysanthemum flower two weeks earlier than        plants of ‘Vigorelli Dark Orange’.    -   3. Ray florets of plants of the new Chrysanthemum are initially        red purple in color becoming greyed orange in color with        subsequent development giving the inflorescences a bi-colored        appearance whereas ray florets of plants of ‘Vigorelli Dark        Orange’ are initially dark red in color becoming dark orange and        lighter orange in color with subsequent development giving the        inflorescences a bi-colored appearance.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of thenew Chrysanthemum plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. The photographcomprises a side perspective view of a typical flowering plant of ‘AduroBronze’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations andmeasurements describe plants grown in 19-cm containers in an outdoornursery in Oostnieuwkerke, Belgium during the summer and autumn andunder cultural practices generally used in commercial Chrysanthemumproduction. During the production of the plants, day temperatures rangedfrom 20° C. to 25° C. and night temperatures ranged from 12° C. to 18°C. Plants were 20 weeks old when the photograph and detailed descriptionwere taken. In the following description, color references are made toThe Royal Horticultural Society Colour Chart, 2005 Edition, except wheregeneral terms of ordinary dictionary significance are used.
